Line, the embodiment of the present invention is to this without limiting.
As shown in Fig. 2, the antenna tuning method includes:
Step 201: in the case where first antenna is in running order, the second antenna is in standby, obtaining first
First working frequency range of antenna.
In general, the same antenna can receive or emit the signal of different frequency range, therefore, first antenna is in running order
When, when the second antenna is in standby (i.e. off working state), obtain working frequency range (the i.e. first work frequency of first antenna
Section).
Step 202: according between the working frequency range of pre-set first antenna and at least two second radio frequency paths
Corresponding relationship determines target radio frequency access corresponding with the first working frequency range at least two second radio frequency paths.
In the embodiment of the present invention, pre-set between each working frequency range of first antenna and each second radio frequency path

Step 203: the second antenna and target radio frequency access is connected in the second power amplification unit of control.
After determining corresponding with the first working frequency range target radio frequency access, the second power amplification unit of control is connected the
Two antennas and target radio frequency access.Due to being connected with the second load on the second radio frequency path, when the second antenna is penetrated with target
When frequency access is connected, the input impedance of the feeding point of the second antenna can change, between the second antenna and first antenna
Under coupling, the impedance based on Smith's parameter, which is drawn, to be realized to first antenna by the second antenna, adjusts first antenna
The input impedance of feeding point improves the working efficiency of first antenna so as to adjust the radiant power of first antenna.
For example, antenna efficiency is relatively low as shown in figure 3, first antenna work is in the frequency of 1850MHz to 1950MHz
(as shown in the block curve in Fig. 3).From the figure 3, it may be seen that it is logical to connect different second radio frequencies when first antenna is in running order
Road can optimize the antenna efficiency of first antenna different frequency scope, therefore, pass through leading for the second antenna and the second radio frequency path
